Protect the eyes there are two "golden period"

Many students are not very old mirror age is not small. Why the child's eyes lost their luster? People's Liberation Army No. 254 Hospital of experts believe that the child eye development there are two "golden period", during this period can not be scientifically protect the eyes, the eye involvement will lead to premature variation of vision.
The experts say that the eyes of two important stage of rapid development. The first stage is about 3-4 years old, the second phase of puberty, around 12-15 years old. Adult vision of the good or bad, with these two "golden period" is closely related. Eyes in the developing, the younger, faster development. Eyes whether the healthy development by proportional to the stimulus; stimulate the smaller the better development, and vice versa.
The expert further explained that the main cause of myopia is to close a long period of stimulation accelerated eye from hyperopia state to face up to the status change. A "golden period", although the child's eyes in the hyperopia stage, but if given a long time close stimuli, such as watching TV, playing video games, reading, literacy, etc., is bound to accelerate the speed of the eye longer. Similarly, in the second "golden period", the heavy academic burden, fatigue use of the eyes will speed up the axial length. This allows the face of the eye was supposed to develop into the age of 18-20 and forced into early years to become face up to. The eye has not yet mature, it is constantly stretched in the axial growth, the gradual formation of myopia.

Myopic eyes just for close work, wear glasses to read will make this state is broken, the eyes will seek a new balance on this basis, to deepen the degree of eye, the pace of development of myopia will significantly speed up.
